먼저 Attachment 테이블에 max_points 필드를 추가합니다. 여기에서 제공된 예에 따르는 경우 webapp/models.py 파일에 포함됩니다.

# Database model to represent an attachment.
class Attachment(db.Model):
    # The attachmentId is the unique identifier for the attachment.
    attachment_id = db.Column(db.String(120), primary_key=True)

    image_filename = db.Column(db.String(120))

    # The image caption to store.
    image_caption = db.Column(db.String(120))

    # The maximum number of points for this activity.
    max_points = db.Column(db.Integer)
